Abstract:Research on the coordinated development of green finance and industrial green is of great value for promoting highquality economic development and ecological construction. Based on the coupling mechanism of green finance and industrial green development, the article constructs a model of coupling coordination degree. Using the data of nine provinces and two cities in the Yangtze River Economic Belt from 2012 to 2017, it analyzes the coupling and coordination relationship between green finance and industrial green development. The results show that, firstly, the development of green finance promotes green industrial development, and the green development of the industry has achieved remarkable results in feeding back green finance. The green finance and industrial green development of the Yangtze River Economic Belt have reached a benign resonance coupling, and the degree of coupling and coordination has been continuously improved. The development stage has gone through reluctant coordination, primary coordination, intermediate stage to good coordination, and is moving closer to highquality coordination. Secondly, the industrial green development in the upper reaches of the Yangtze River Economic Belt has formed an intraregional cooperation mechanism. Therefore, the green industry in this region has developed rapidly, and the coupling and coordination of green finance and industrial green development has risen the fastest since 2012. Thirdly, the nine provinces and two cities in the Yangtze River Economic Belt differ in the degree of coupling and coordination between green finance and industrial green development because of their different foundations and priorities. But they have reached the stage of good coordination. Finally, corresponding countermeasures and suggestions are put forward for the current situation of the coupling and coordination of green finance and industrial green development in the Yangtze River Economic Belt.
